The internal switches in all-photonic networks do not perform data conversion into the electronic domain. Although this removal of O-E-O conversion eliminates a potential capacity bottleneck, it also introduces scheduling challenges; photonic switches cannot perform queuing operations, so traffic arrivals at these switches must be carefully scheduled. The(More)
— In this paper, we propose an off-line scheduling algorithm for an optical TDM/WDM star network composed of a non-blocking optical central switch and a set of edge switches, each capable of simultaneously transmitting (and receiving) at several different wavelengths. We implement a scheduling algorithm, which assigns a cost to each time slot destined to a(More)
Internal switches in all-photonic networks do not perform data conversion into the electronic domain, thereby eliminating a potential capacity bottleneck, but the inability to perform efficient optical buffering introduces network scheduling challenges. In this paper we focus on the problem of scheduling fixed-length frames in all-photonic star-topology(More)
Internal switches in all-photonic networks do not perform data conversion into the electronic domain, thereby eliminating a potential capacity bottleneck, but they introduce network scheduling challenges. In this paper we focus on scheduling fixed-length frames in all-photonic star-topology networks. We describe the Fair Matching (FMA) and Equal Share (ESA)(More)
This paper describes a framework for fixed-length frame scheduling in all-photonic networks with large propagation delays. We introduce the Fair Matching Algorithm (FMA), a novel scheduling approach that results in weighted max-min fair allocation of extra demands, achieves zero rejection for admissible demands, and minimizes the maximum percentage(More)
We introduce an intelligent system to optimize a team composition based on the team's historical outcomes and apply this system to compose a surgical team. The system relies on a record of the procedures performed in the past. The optimal team composition is the one with the lowest probability of unfavorable outcome. We use the theory of probability and the(More)
